iOS/Mac: Sometimes, you just need to get something from your Mac to your iOS device instantly (or vice versa). Command-C is an (awkwardly named) app that makes it so you can copy clipboard data—that includes images or text—across iOS devices or between Mac and iOS.

Command-C is basically a shared clipboard that all your devices have access to. Copy something to your Mac's clipboard and it's available on your iOS device. Do the same on your iPhone, and you can grab it on your Mac, or even toss it over to your iPad. All you need to do to share data is click the share button on your computer or open the app on iOS and and the clipboard is copied over immediately. From there, you can share images, text, rich text, or URLs. If you bounce between different devices for work, Command-C is worth having around.
